Search for NMSSM Higgs bosons in the h->aa->mumu mumu, mumu tautau channels using ppbar collisions at sqrt{s}=1.96 TeV

TL;DR

This paper reports a search for lightest neutral Higgs bosons in the NMSSM model decaying into pairs of muons and taus using proton-antiproton collision data at 1.96 TeV, setting limits on production without observing a signal.

Contribution

First search for NMSSM Higgs bosons decaying into muons and taus in proton-antiproton collisions at Fermilab.

Findings

No significant signal observed.

Limits set on Higgs production as functions of M_a and M_h.

Abstract

We report on a first search for production of the lightest neutral CP-even Higgs boson (h) in the next-to-minimal supersymmetric standard model, where h decays to a pair of neutral pseudoscalar Higgs bosons (a), using 4.2/fb of data recorded with the D0 detector at Fermilab. The a bosons are required to either both decay to mu^+mu^- or one to mu^+mu^- and the other to tau^+tau^-. No significant signal is observed, and we set limits on its production as functions of M_a and M_h.
